THE LOGIC AND METHODOLOGY OF CHECKLISTS
por Jenny Jenkins
1. Value of Checklist
1.1. Mnemonic Devices: Good for memory
1.2. Easier for Stakeholders to understand and validate theories
1.3. Reduce influence on overemphasizing merit (Halo Effect)
1.4. Reduce the influence of the Rorschach effect
1.5. Use of a valid comlist eliminates the problem of double weighting
1.6. Incorporates economical format
1.7. Evaluative checklist can be developed more easily
1.8. Help easily develop theories of management
2. Core of COMlists (Watches)
2.1. Accuracy
2.2. Readable Dial
2.3. Durability
2.4. Comfortable to Wear
2.5. Band
3. Refinement of COMlists
3.1. Do not abandon equal weighting without overwhelming evidence
3.2. Make a simple, intuitive estimate of the difference as the basis for a trial exploration of its effect
3.3. If the ratio you pick seems not to apply constantly across the whole range of performance on a particular criterion, try varying it for a certain interval
3.4. Testing your attempts to set differential weights requires some judgment about whether the results show it to have been a success or failure
3.5. A procedure that combines qualitative weighting with minimalist quantitative procedures, called Qualitative Weight and Sum
4. Basic Types of Checklist
4.1. Laundry List
4.1.1. Order does not affect validity
4.2. Sequential Checklist
4.2.1. Must follow sequence to keep valid
4.3. Iterative Checklist
4.3.1. "KEC": puts forth cost before comparison
4.4. Diagnostic Checklist
4.4.1. Used by taxonomist, mechanics
4.5. Criteria of Merit Checklist (COMlist)
4.5.1. Judges use when rating entries
4.5.1.1. Often tough to develop or validate
